M3 () is one of the five lines of the
Bucharest Metro. M3 Line runs from
Anghel Saligny
Anghel Saligny (; 19 April 1854, Șerbănești, Moldavia – 17 June 1925, Bucharest, Romania) was a Romanian engineer, most famous for designing the Fetești-Cernavodă railway bridge (1895) over the Danube, the longest bridge in Europe a ...
to
Preciziei. It is the east-west line of the system.
The line shares and 7 station with M1.
History
The first part of the present-day M3 to be built was from
Eroilor to
Preciziei (at the time known as Industriilor) along with the line to Industriilor depot (nearby the ITB Militari depot), west of the station itself. This section was not a line on its own, but rather a branch of the M1, and it opened on 19 August 1983. During the communist period the 'M3' was the
Gara de Nord -
Dristor 2 section of what is today the
M1. Construction work on another branch, from
Nicolae Grigorescu to
Anghel Saligny
Anghel Saligny (; 19 April 1854, Șerbănești, Moldavia – 17 June 1925, Bucharest, Romania) was a Romanian engineer, most famous for designing the Fetești-Cernavodă railway bridge (1895) over the Danube, the longest bridge in Europe a ...
(at time named Leontin Sălăjan and Linia de Centură), began in 1988, but the work was halted in 1996 and the tunnels were flooded.
Due to the very large gap between
Pacii and
Lujerului (then known as Armata Poporului) construction of
Gorjului started. It was opened in two stages: the westbound platform in 1994 and the eastbound platform in 1998.
In the mid 2000s the route of the M3 was shortened from
Pantelimon - Industriilor to Eroilor - Industriilor and the M3 became a shuttle service, similar to the
M4.
In 2008 was finally also opened as a shuttle the long-overdue section from Nicolae Grigorescu to Linia de Centură, whose construction works resumed in 2004 as an extension of the M4.
Because a line composed of two unconnected shuttles was very impractical, on 4 July 2009 the two branches from Preciziei and Anghel Saligny were linked sharing tracks with the M1 between Eroilor and Nicolae Grigorescu and thus forming the M3 as it is operated today.

The M3 uses
Astra IVA and
Bombardier Movia trains. The IVA trains were used exclusively until 2009, when the first Movia trains were introduced on the M3, and services from
Preciziei to

commenced. In 2014, after the arrival of new
CAF trains and the migration of Movia trains from the
M2 to the M3 was complete, the old trains were no longer needed. IVA trains were reintroduced in 2020, when 8 Movia train sets were transferred to the new
Line 5.
